Looks like the existing check using has_gimple_body_p isn't enough
at LTRANS time but I need to check in_other_partition as well.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.
OK?
Thanks,
Richard.

* tree-ssa-structalias.c (ipa_pta_execute): Check in_other_partition
in addition to has_gimple_body.
* g++.dg/lto/pr97565_0.C: New testcase.
* g++.dg/lto/pr97565_1.C: Likewise.
